The open literature, Federal publications, industrial reports, and other sources published between 1975 and 1980 were reviewed for information relevant to personal air samplers potentially useful in sampling organic compounds at ambient levels (50-200 ppt). Seventy one references which identify fifty two groups involved in developing or marketing relevant instruments are cited. Four passive personal monitors and two active monitors developed for industrial hygiene levels are recommended for further testing and development for use at ambient levels. These monitors are DuPont's PRO-TEK G-AA; Abcor's GASBADGE; 3M's 3500 Organic Vapor Monitor; Real's Mini-Monitor; MDA's Accuhaler; and Bendix's BDX102. Laboratory tests are proposed in the areas of blank reduction/reproducibility, analytical methodology, and controlled atmosphere exposures. Following completion of laboratory tests, the most promising devices should be field tested to determine which monitors provide the most accurate and reliable data.
